Get it professionally installed....heheh. no I'm not joking it is better to get someone to do it, cuz you have to prep the surfaces squeaky clean for the to stick perfectly. You better have gotten dynamat Extreme, that stuff is the best, all the other dynamat is not even close to as sticky nor as good to dampening sound. trust me on all of this info, Me and my brother's completely Dynamated the entire 1994 Sentra LE 4-door with 2 layers of dynamat extreme all around. make sure you poke holes where all the screws go, and make sure you cover everything(including electricals and holes/gaps. Ok let me know if you need more help, but I really suggest getting it professionally installed.
